ANTISKID CHAIN.

. Application filed June 27, 1924. Serial No. 722,781.

In the application of an anti-skid chain of the link 2. This construction is common to the tire of an automobile, the tendency of in anti-skid chains.

the chain is to shorten,due to the fact that It is necessary that the cross chains be arthe cross chain ends lose their natural posiranged directly at right angles to the side 5 tion and swing ba k on the links of the side chains when the anti-skid chain is to be apchains to. which they are connected, with plied to the tire. In removing an anti-skid the result that a wedging as well as a. clamp- 7 chain from a tire, the same is handled rather ing action takes place between the end links recklessly and is frequently thrown in a heap of the cross chain and the last mentioned under a seat inthe automobile. The result 10 links of the longitudinal chains. When these isthat the end links 1 of the cross chains ride chains become so fastened together, it is a over the rounded end 6 of the link 2,v to tedious, job in straightening the -same,'that' which they are connected'to force the link 4 is, in again bringing the cross and the lonat an outward angle with respect to the link gitudinal or side chain links in proper posi 2 and likewise to effect both amvedging and whe l, links 1 and '2 and the eyes 5 of the link 1.

It is therefore to be considered the object WVhen the links are thus bunched together it.

of this invention toproduce a simple means is frequently necessary to employ a wedge,

' for preventing such wedging or looking enhammer or the like to disengage the same.

2 gagement between the end links of the cross Nith my improvement, however, such bunchchains and the link of the side chain to ing and wedging of thelinks is entirely over 7 which the link of thecross chain is concome. On the outer arm of the link 2 I senected. cure or form a longitudinal enlargement ino the attainment of the foregoing object, cheated by the numeral 7. The enlargement 25 reference is to be had to the drawing which 7 is in the nature of a split sleeve and is of.

accompanies and which forms part "of this a length approximately equalling that of the application. 7 side of the link on which it is arranged.

In the drawing z- The sleeve is open when arranged on the igure 1 is a fragmentary plan view of an link and is closed and compressed against anti-skid chain showing the link of one of the link by the simple employment of .a pairthe side chains to which the end link of one ofpincers or the like. The enlargement preof the cross chains is attached provided with vents the eye 5 of the link 4 traveling a dea means for preventing a biting or wedging termined distance over the rounded end 6 of action between the said link of the cross the link 2 so that the eye end of the cross 35 chain and the link connected with the first link 1 cannot be brought to the position illusmentioned link ofthe side chain. trated in Figure 3 of the drawing and conse- Figure 2 is a sectional view on the line quently cannot exert any. binding action 2-2 of Figure 1. against the eye 5, the rounded end 6 of the Figure 3 is a fragmentary plan view to' link 2 and the eye end of the link 1. f illustrate the manner in which the end links Having described the invention,I claim 1 of the cross chains effect a wedging and Incombination with an anti-skid chain, binding action upon the links of the side extending side chains and cross chains whose 1 chains. 1 end links are connected to certain of the links 1 I A port-ion of a side chain and a portion of the side chains, of a split metal sleeve ar- 45 of a cross chain of an anti-skid chain for ranged on and secured to that arm ofthe automobiles has been illustrated by the link opposite thearm to which the end link drawing. The end link of the cross chain is 'of the cross chain is connected, and said 7 indicated by the numeral 1, and the linkof sleeve being of a length approximately equal the side chain to which the same is connectto that of the arm of the link to which it is i 50 ed is indicated by the numeral 2.
